TO ALL 'WHOM IT MAY CONCERN:

Be it known that I, ARTHUR A. MAXWELL, of Pratt, ,in the county of Shelby, and inthe State of Ohio, have invented certain new and useful .Improvements in Grading and Ditchin'g-Machines; anddo hereby declare that the following is a full, clear, and 'exact description thereof,.reference being had to the accompanying drawings, and tothe letters o f reference marked thereon. Y. f

In the-annexed drawings, makingpartfof this specication, Arepresents the frame of the machine, which is constructed ina verystrong and substantial manner, and supported at its rear end upon the wheels G G'.

B lrepre'sent two ploughs', which'lsupport theforward end of the frame., The mould-boards of these ploughs turn inward. The forward end ofthe frame is connected, by means' of a cle'vis, to a wheel R. The clevis embraces the`wheel, and a'pinpasses through the Wheel, near its periphery, and through the clevis, coniining I them together. This wheel R is on the shaftof a truck, N. The drivers seat is also upon-this truck. A shaft, W, with a crankaxle upon it, lies and has its bearingsin'twoluprights e e, which are erected upon' the truck,

, and upon this shaft is a wheel, S, and also a small ratchet-wheel. A band,-T, passes from wheel S to and around wheelR; The-driver, sitting in the seat V, by turning the crank'of shaft W, causes, through wheel S and band T, the wheel R to make a'partialprevolution backward aud forward, for the purpose of raising and lowering the forward end of the frame A. The dogkU catches into the ratchet-wheel on shaft W, to station said shaft, and consequently the frame A, in any desired position. C represents au inclined plane, within the frame A, and running from a'level with the bottoms ofthe plougbs up, at an angle of about forty-iive degrees with the frame,

. untilit meets an endless belt, D. The endless belt D revolves aroundsuitable rollers, which are secured in the frame, and has upon its outer face slats, so that it will carrylup ear'thwhe'n deposited upon it,

At right angles to and in rear of `frame A is a frame, E, 'which has within it an endless belt, F, which revolves around suitable rollers. The b elt F is situated below the belt D, so that the earth which is carried up by the .belt D can be deposited upon it. The belt F is revolved by means of a band, J, which passes around a pulley,

K, upon oue'of the 'and rollers of the ben. The band J passes around A puuey upon Shaft H, and shafnH is driven by means of a gearswheelon Athe inner face of the driving-wheel G', which plays into a pinion, I, upon shaft H. The belt-F isfrevolved so as to'carry 4oii'the earth deposited upon it by belt fD.v flBelt D is driven by means of a bandyRwhich passes from a pulley ou the injner face of driving-,wheel-G-to and around a pulley, L, on one ofthe-'end' rollers of this belt. .Suitable levers, as seen at o and al, are used for throwing the pulleys which commun'icatemotin to the belts out and in gear. 'These may be arranged in anyof the known and usual ways. r

In using this machine, power is applied to the truck N, which drags the machine behind it. The ploughs enter and loosen up the earth, and the earth between the ploughs, thus loosened,'passes lup the inclined plane C onto the belt D, and is carried up, and, yby belt D,emptied upon the belt F. This latter Abelt carries the earth away to one side, and out of the way of the machine. 'I

' Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

The frames A E, ploughs B B, inclined plane C, belts D F, wheelsR S, band T, and truck N, with crankshaft W, the whole arranged and combined with their respective devices for operating in the manner substantially as and for the purposes specied.

In testimony that I claim the foregoing, I havefhereunto set my hand, this 9th d'ay of September, 1867.

ARTHUR A. MAXWELL.
